### Questions for you ### Decisions (Paul, Nov 2026)
- **Extendable, not finished:** the Ember has a last boss, and after it you
keep playing. The chain is built so more worldlets (and crossings) can be
added after the Ember later: each worldlet names the next, nothing assumes
the Ember is the end.
- **The crossings:** tunnel, sail, climb, burrow, in that order.
- **Harder by biome, not just by numbers:** each worldlet has its own,
stronger animals and its own hazards. The Marsh, for one: mosquitoes whose
bites can make you sick, and bog, mist and the like. Others in the same
spirit per biome (to design with each worldlet).
- **Multiplayer:** leaning to *spread out* (each player goes where they
like), if a server can run several worldlets at once. A measurement of
today's server, in the next section, says whether it can.
### Server cost, measured (0.3.1)
One worldlet, a dedicated server on the M5 Pro, never pausing: about
**12% of one CPU core and 270 MB of memory**, with nobody on. Players add
creatures, weather and pickups around them. So with *spread out*, the worst
case of 8 players in all 5 worldlets is about five of today's servers in
one process: roughly 1.4 GB and a little over half a core before players,
and worldlets with nobody in them stand still and cost next to nothing.
Comfortable on the home Mac; a small cloud server (2 GB) would be tight.
### Questions still open
1. **Multiplayer:** spread out (confirm, now the cost is known), or everyone
together after all?
